My Superfi5Pro's are busted and going back for replacement (warning to UE owners ... they tried to enforce the Logitech 1 yr warranty on me when I bought my Superfi's under the old UE 2 yr warranty) ... anyway, those Superfi5Pro's get used about 99.99% of the time, because they really are portable. I also have the ATH-ES7, but I rarely put it to use because they're kind of impractical as a portable (for me). Most of my listening is done outside the home (at work and while exercising) so real headphones hardly ever fit into my schedule. So anyway, got the ES7 out tonight and listened to NY's album "After the Gold Rush." So nice. The ES7 is very well suited to this album, but still ... all you guys who listen to your IEM's all the time due to the convenience ... get some real headphones on and listen. That is all.
